The Dallas Cowboys had a nearly full hockey-style line change within their coaching staff. That means new ideas and new philosophies will be injected into a team that spent nearly a decade under former head coach Jason Garrett. It also means no preconceived notions about the current roster in Dallas or any sense of investment.
For instance, the prior coaching staff invested nearly four years attempting to make college basketball star Rico Gathers into an NFL tight end only to release him last year with three career receptions under his belt. The new staff would have likely cut ties much sooner with someone like Gathers as they would have had a non-biased view of the player, regardless of the time invested.
